Might not kill a tube, but it could kill a builder! Be careful!! Oh, come on. How could anyone have not touched a low-kilovolt B+ and call himself a ham? We've all touched a kilovolt or two, probably as young kids, and we're all perfectly normal! Tim. |

Well, all humor aside, I stand by my original answer to BE CAREFUL.
True, a KV might not kill you, but if you start out being careless, when you progress up to tubes like a 4-1000A, the B+ will most certainly kill you. The pile of ashes on the floor will be proof enough ![]() Again, humor aside, I pride myself on NOT having hit a KV...that takes more skill than hitting it ![]() Scott N0EDV Tim Shoppa wrote: On Aug 23, 9:17 pm, Scott wrote: Might not kill a tube, but it could kill a builder!

At least in Europe AC/DC radio and television receivers were common, in which you could have the 220 V mains directly in the chassis.

There was a golden rule of always keeping your left hand in your pocket while working with your right hand inside a mains powered or high voltage device. An AC/DC powered device could deliver quite a lot current through the mains fuse and rectifier. If you touched some high voltage part (possibly causing a cramp in your hand), the current would not go through your hart and you would have the other hand operational to pull the plug. --- When testing a new power supply, I was sniffing around to detect any overheating components, my nouse touched the mains transformer primary and got an electric shock in my nouse. I did not notice anything special after that, but driving a car immediately after that proved to be difficult, since I really had to concentrate to stay in the lane. So if you get an electric shock in the head, nouse or ears, please avoid driving a car for a few hours, at least for the safety of others using the road :-). Paul OH3LWR |
